Questions: A three-phase power system network consisting of 6 buses is as shown in Figure 1. G6 The reactance of the lines in the network 2 G2 6 5 shown in Figure 1 is: Reactance, X From Bus To Bus (p.u.) 1 2 0.07 1 6 0.29 2 3 0.17 2 5 0.17 2 6 0.15 3 4 0.30 4 5 0.25 5 6 0.16 Figure 1 Generator 2, G2 has a reactance X=0.06 p.u. Generator 6, G6 has a reactance X = 0.05 p.u. Task 1: Manual calculation Using hand calculation (type-written or hand-written), calculate the fault current, voltage at each bus and current in each line when a symmetrical (balanced) three-phase fault occurs at bus 5 in the given power system network. The fault impedance is 0 p.u.
